3 Claims; (01.156-44) This invention relates to awning supports, and hasfor-an object the provision of an awning supporting arm, which may beadjusted to vary the distance of the outer end of the arm from itssupport and the height of the end of the said arm above the sidewalk,with a corresponding change in the relation of the awning supported uponthe said arm. I v v The invention has in view an awning support '1adapted, to be afiixed to the front of buildings for supporting anawning in position to give the required shade to the windows or storefront, and for this purpose the said arm is provided with means forproducing a step-by-step adjustment of the elevation of the awningsupport, as well as small increments of adjustment, without altering orchanging the attachment thereof to the building. q

Another object of the invention is the pro vision of an awning armconstructed to fold to an upright, collapsed position again'stthe wallof the building, so that it takes upas little room as possible when insuch position.

With these and other objects in view, the invention resides in the novelfeatures of construction and arrangement of parts which will be morefully described and claimed hereinafter.

The invention is shown in the accompanying drawing in which 7 Figure 1is a side elevation, showing the awning side arm in extended position,and in dotand-dash outline the said arm in collapsed or folded position;

Fig. 2 is a top plan arm;

Fig. 3 is a cross-sectional view through one of the brackets forattaching the arm to a building, and showing a portion of the means foradjusting the arm;

Fig. 4 is a vertical sectional view on the line 4-4 of Fig. 3. In thedrawing illustrating the preferred embodiment of the invention, a singleawning side arm is shown, it being understood that one such arm isapplied to the building at each side of a window or store front. A bar11 is arranged between the outer ends of said side arms, to which barthe outer end of the awning 12 is secured.

The arm 10 comprises a lever arm 13 pivotally mounted at its lower endto a bracket 14, which bracket is adapted to be secured to the face of abuilding, indicated in the drawing by the line 15, by any desired means,such as screws 16. The opposite end of the lever arm 13 is pivoted to anarm 17, and between its ends to an arm 18 at the point view of theawning side while each of the arms 1'7 and 18 consists of a pair of barsof channel formation, between which the arm 13 is pivoted, ashereinbefore described. Theinner end of the arm 18 is pivoted to theouter end of an adjustable lever arm 20, the opposite end of which leverarm is pivotally connected between the lugs of a slide 21. The saidslide 21 is movable on a bar 22 of a bracket 23 and is adapted to besecured in various positions thereon,,to provide a step-by-ste'padjustment of the point of attachment of the said slide on said bar,with a corresponding change in elevation of the outer end of the lever10. The bracket 23 isadapted to be secured to the wall of a building'in' vertical alignment with the bracket 14.

The arm 18, at its outer end, is pivoted to'the inner end. of anoutwardly-extending arm 24, and between'its ends the arm 24 is pivotallyconnected at 25 to the outer end of thearm 17. This constructionprovidesa pair of leverswhich may be folded to an upright, collapsed condition,and when in extended position provides a means of support for theawning, which may be adjusted to change the height of the awning abovethe side- 19. The lever arm 13 is preferably a flat bar,

walk and the distance of'the outer edge of the awning from the building.

To provide both small increments of adjustment and step-by-stepadjustments of the said distances, the lever arm 20. is made adjustablein length, and the slide 21, to which the said arm 20 is pivotallyconnected, is adapted to be secured at different positions on the bar22, as hereinbefore described. As shown in the drawing, the slide 21 isprovided with a set screw 26, which is adapted to engage any one of thedepressions 27 in the bar 22, to hold the slide in fixed positionthereon. The bar 22 may be of any desired length and the depressions 2'7spaced along the bar to provide the step-by-step adjustment that isdesired. The lever arm 20 may be lengthened to provide either very smallincrements of adjustment or a relatively large degree of adjustment. Asshown in the drawing, the length of this lever arm may be changed byrotating the sleeve 28 to produce a spreading apart of the threaded bars29 and 30, one of said bars being provided with a right-hand thread andthe other with a left-hand thread, which engage the correspondinglythreaded bore of the sleeve 28. It will be understood, of course, thatby turning the sleeve 28 a fraction of a turn, the degree of adjustmentimparted to the outer end of the arm 24 is relatively small, and turningthe sleeve a number of turns will impart a correspondingly greateradjustment both as to the distance of the outer end of the arm from thebuilding and the height of the outer end from the sidewalk.

In order that the side arm 10 may be arranged in compact formation whenin collapsed condition, the ends of the arms 13, 18 and 24 are eachcurved so that when the support is in vertical position, these arms willcome together in substantially parallel alignment. For this purpose alsothe end 32 of the lever arm 20 is offset, so

that its pivotal connection with the lever 18 will permit the said barsto be arranged in substantially parallel relationship when in collapsedcondition.

The awning 12 is wound on a spring roll 31 attached at its ends to thebuilding above the awning support, the outer end of the awning beingaflixed to the bar 12 connected between the ends of the arms 24, ashereinbefore described. By means of the spring roll any slack in theawning will be taken up, and when the awning arm is arranged incollapsed condition substantially the full length of the awning will berolled up on the said roll.

What is claimed is:

1. An awning support comprising in combination with a verticallyswingable side arm structure, including a pair of relatively swingablelever arms, one'of which arms has a fixed fulcrumed connection with asupport; means for supporting the other lever arm for verticaladjustment, said means including a bracket having upper and lowerportions for attachment to said support, one of said portions having anopening therein, a bar of rectangular shape in cross section connectedwith'the other of said portions and with its free end disposed in theopening of said first mentioned portion, a member having a rectangularopening for receiving said bar and on which bar the said member isvertically slidable, said member having forwardly extending furcations,a longitudinally extensible link having one end disposed between andpivotally connected with said furcations and a pivotal connectionbetween the other end of said link and said other lever arm to permit ofvertical swinging movement, said bar having a series of depressions andsaid member having means for selective engagement with said depressionsfor securing the member and link in vertically adjusted positions.

2. An awning support comprising in combina-- tion with a verticallyswingable side arm structure, including a pair of relatively swingablelever arms, one of which arms has a fixed fulcrurned connection with asupport; means for supporting the other lever arm for verticaladjustment, said means including a bracket having upper and lowerportions for attachment to said support, a bar of rectangular shape incross section bridging the said upper and lower attaching portions, amember having a rectangular opening for receiving said bar and on whichbar the said member is vertically slidable, said member having forwardlyextending furcations, the other lever arm being pivotally connected atone end with said furcations for vertical swinging movement, and meanson the said member engageable with the said bar for selectively securingthe member and lever in vertically adjusted positions.

3. An awning support comprising in combination with a verticallyswingable arm structure, including a pair of relatively swingable leverarms, one of which arms has a fixed, fulcrumed connection; means forsupporting the other lever arm for vertical adjustment, said meanscomprising a vertically disposed non-circular guide element attached tothe wall front in spaced parallel relation thereto, a non-rotary slidemounted on and surrounding said guide element for verticaladjustment'and with which member said other lever arm has a fulcrumedconnection and means on the guide element engageable with the slidemember for selectively locking the slide member in one of a number ofvertically adjusted positions.
